It is normal to lose some hair every day. Most medical studies show that losing up to 100 strands of hair a day is considered normal. Cases where daily hair loss can exceed this, or if you have a family history of hair loss, though, can become problematic. Consistent and excessive hair loss can leave you with bald spots if you are a man, or thinning hair on top of your head if you are a woman. While many people, from both genders, can suffer from this type of hair loss by the age of 50, there are also many cases of this disorder surfacing in patients who are much younger. Let’s look at this disorder in some more detail. Losing hair is part of a normal cycle of growth and replacement. Hair follicles go through the growth and resting cycle in a non-synchronized way. Genetics is the most common cause of hair loss among both, men and women. In fact, heredity accounts for 95% of all the cases of alopecia (baldness). The remaining 5% of the cases can depend on a number other factors like diet, stress, illness, medications and more.
